Connecting and Configuring Ethernet
Connect one end of the CAT-5 patch cable supplied with your RTM3205 to either of the RJ-45
connectors labeled 10/100/1000BASE-T. Connect the other end of the patch cable to your network
through a ‘straight’ port on your switch. Do not connect it to a ‘crossover’ port on your switch.
By factory default, the RTM3205 will attempt to configure the Ethernet interfaces automatically via
the Dynamic Host Configuration Protocol (DHCP). The RTM3205 will attempt to set the netmask,
its IP address, the IP address of the default gateway, the domain name and the IP addresses of any
nameservers, if the DHCP server is configured to provide them. You may optionally configure the
RTM3205 to also set its hostname via DHCP, if your DHCP server is configured to provide it. You
can do this by running a simple script called
netconfig
after your unit is up on the network.
If your network
does
use DHCP for host configuration, and you are in a hurry to get your RTM3205
up and running, you may proceed to
Verifying Network Configuration
to make sure that the network
parameters were set up correctly. Otherwise, it is recommended that you read the following sections
on the use of the RS-232 serial I/O port now, since they will help you in debugging any problems that
you may encounter with the automatic configuration via DHCP.
If your network
does not
use DHCP, you will need to configure your Ethernet interfaces using the
RS-232 serial I/O port. The following sections contain brief descriptions on how to do that.
Configuring Ethernet with the Serial Port
To configure your Ethernet interfaces with the serial port, after logging in as the
root
user, you must
run a simple script called
netconfig
. This script will prompt you for the needed information and
perform some syntax checking on your inputs. Then it will create or modify the appropriate files
needed to configure the Ethernet interface. The following sections will guide you in setting up com-
munications with the RTM3205 using its RS-232 serial I/O port.
Connect the RS-232 Serial I/O Port
To test serial communications with the RTM3205 you will need either a VT100 compatible terminal
or a terminal emulation program running on your computer. We will refer to either of these as “termi-
nal” for the remainder of this instruction.
1. Disconnect power from the RTM3205.
2. Connect one end of the DB9F-to-DB9F null modem adapter cable to the serial I/O jack on the
RTM3205.
3. Connect the other end of the DB9F-to-DB9F null modem adapter cable to the terminal. If the
serial I/O port on your terminal does not have a DB9M connector, you may need to use an adapter.
Refer to
Appendix K - Specifications
for details on the signal wiring.
If you are using a computer
for your terminal, remember which port you are using because you will need to
know that in order to
set up your terminal software.
